DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of an electronic device 100 with switchable input modes is illustrated. In the embodiment, the electronic device 100 includes a key input mode and a touch input mode. In the key input mode, users can only input symbols or commands to the electronic device 100 through pressing keys of a keyboard of the electronic device. In the touch input mode, users can only input symbols or commands to the electronic device 100 through touching a touch screen of the electronic device 100.
The electronic device 100 at least includes a keyboard unit 10, a touch unit 20, a switch unit 30, a storage unit 40, a processing unit 50, and a display unit 60.
The keyboard unit 10 includes a key input unit 110 and a key input processing unit 130. The key input unit 110 is configured for generating input signals in response to user input. The key input processing unit 130 is configured for processing the input signals transmitted from the key input unit 110 and transmitting the processed input signals to the processing unit 50.
The touch unit 20 includes a touch input unit 210 and a touch input processing unit 230. The touch input unit 210 is configured for generating input signals in response to user inputs. The touch input processing unit 230 is configured for processing the input signals transmitted from the touch input unit 210 and transmitting the processed input signals to the processing unit 50.
The switch unit 30 is configured for generating a switch signal in response to user inputs. The switch unit 30 can be a physical key or a soft key expressed by a displayed icon.
The storage unit 40 is configured for storing a predetermined time interval T.
The processing unit 50 includes a timing module 510, a comparing module 530, and a switch controlling module 550. The timing module 510 is configured for recording a duration T1 of the switch signal transmitted from the switch unit 30. The comparing module 530 is configured for comparing T with T1. In the embodiment, if T1 is equal to or greater than T, the comparing module 530 generates a touch input switch signal. If T1 is less than T, the comparing module 530 generates a key input switch signal. In an alternative embodiment, if T1 is equal to or greater than T, the comparing module 530 generates the key input switch signal, and if T1 is less than T, the comparing module 530 generates the touch input switch signal. The switch controlling module 550 is configured for switching the key input mode to the touch input mode according to the touch input switch signal, or switching the touch input mode to the key input mode according to the key input switch signal.
The display unit 60 is configured for displaying a graphic user interface. In the embodiment, the display unit 60 is a touch screen.
FIG. 2 is a flowchart of a method of switching input modes of the electronic devices 100 in accordance with an exemplary embodiment.
In step S210, the switch unit 30 generates a switch signal in response to user inputs.
In step S220, the timing module 510 records T1 of the switch signal.
In step S230, the processing unit 50 obtains the T from the storage unit 40.
In step S240, the comparing module 530 compares T1 of the switch signal with T. If T1 of the switch signal is equal to or greater than T, the comparing module 530 generates the touch input switch signal, and the procedure goes to step S250. If T1 of the switch signal is less than T, the comparing module 530 generates the key input switch signal, and the procedure goes to step S260.
It should be noted that in an alternative embodiment if T1 of the switch signal is less than T, the comparing module 530 generates the touch input switch signal. If T1 of the switch signal is equal to or greater than T, the comparing module 530 generates the key input switch signal.
In step S250, the switch controlling module 550 switches the key input mode to the touch input mode.
In step S260, the switch controlling module 260 switches the touch input mode to the key input mode.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
